+## 本科接入
+
+学校列表现有电子科技大学（研究生）、电子科技大学（本科生），连接目标使用稳定标识并保存本机。研究生沿用专用SSO及自动读取；本科使用独立连接器，学校浏览器均延迟到真正访问时创建。
+
+本科课表从 `https://eams.uestc.edu.cn/eams/` 登录，学生自行打开课表、选择学期，再点击「导入当前课表」。同源框架及实际学期字段用于解析；停课周不生成课程，完整教师/教室、跨周变更与备注保留。新课表学期需设置开始日；同学校同学期更新保留日期和偏好。本科12节，第12节22:00–22:45。
+
+本科考试访问 `https://eams.uestc.edu.cn/eams/stdExamTable!examTable.action?semester.id={id}&examType.id={type}`。523为2026–2027第一学期，相邻学期编号差20；1期末、2期中、3补考/缓考。选择一个学期和至少一种类型，全部成功后一次保存；失败、取消、超时保留旧数据。重新认证后全部类型重读，验证码等待不算超时。成功选项用于刷新；历史本科考试不改变课表及开始日。
+
+真实本科课表附件已验证10门课程、18段安排、3段含第12节；考试附件4条属于503，未被默认523污染。仓库只保留脱敏样例。真实账号在线认证、回调和验证码仍需本人验证；附件和模拟回调不替代这项确认。

+# TPSchedule 0.7.0+18：本科生接入验证
+
+2026-10-15。工程位于F:/program/app，原应用名、包名com.tpschedule.app和签名保持。
+
+## 实现
+
+- 学校列表新增电子科技大学（本科生），学校选择使用稳定标识保存；取消或保存失败不开始登录。
+- 本科课表在学校原网页登录、选择学期并打开课表后，点击「导入当前课表」。课表刷新和更新学期沿用手动流程。HTML/HTM离线导入也支持本科结构。
+- 本科考试选择一个学期、多选期末/期中/补考缓考，按类型1→2→3读取，全部成功才保存；失败、取消、超时保留旧数据。认证恢复时丢弃旧片段、整批重读。成功查询选项持久保存供刷新使用。
+- 523对应2026–2027第一学期，每相邻学期编号差20。考试学期独立保存，历史本科考试不改变当前课程、课表学期和开始日。
+- 本科12节，第12节22:00–22:45；研究生及示例11节。七天同屏，教师和教室完整显示，相同节数课程条等长；课程详情保留课程代码和备注。提醒和日历结束时间覆盖第12节。
+- 旧保存格式仍为schemaVersion1，新增字段兼容默认研究生；学校/学期损坏和本科第12节来源缺失拒绝保存或恢复。页面变动/取消时在保存队列内部再检查有效性，避免旧回调写入。
+- Android实际检查发现网页加载前的一次状态探测可能读到旧空白文档；已补回归并改为加载完成后探测，再重建发布和调试包。
+
+## 检查结果
+
+- 完整Flutter套件241项通过；flutter analyze无问题。研究生及本科两个Node页面捕获脚本测试通过。
+- 原本科课表附件解析10门课程、18段上课安排，3段包含第12节；逐节逐周对照保留全部有效安排，停课周扣除。原考试附件4条属于503，外层默认523没有污染实际学期。仓库仅保存脱敏等价样例。
+- 核心回归覆盖人工登录等待超过120秒、单项45秒/整批120秒超时、最后一项失败、整批重新认证、关闭页面、过期回调、保存失败、旧研究生导入、来源损坏、第12节提醒/日历、换周动画、完整教师、课程条长度及慢启动。
+- Android16/API36模拟器覆盖安装后11条原课程仍在。随后通过安卓文件选择器导入脱敏本科HTML：预览18条、提示新学期开始日、设置2026-09-07后显示12行及22:00–22:45；多教师完整显示。历史503考试导入4条，课表523、18条课程及开始日保持；考试选项取消不改成功选项，重启保持学校与数据。
+- 发布包及调试包构建成功；包名com.tpschedule.app、versionName0.7.0、versionCode18。新旧证书逐字节相同，原私有签名文件摘要相同，登记冻结清单18项复核无变化。
+- 模拟器使用软件兼容图形模式；未修改安装包的默认手机渲染设置。既有SDK XML版本提示仍出现，构建成功。
+
+## 交付与实际边界
+
+发布APK：59991887字节，SHA256 `D813F9FB6D33F4DE9A1116DF35EE66BBF8475E09DD1D536C50DFE017DFDBD1BE`。调试包、源码包及截图在dist中；保留TPSchedule-0.6.2.apk。
+
+截图含学校列表、本科浏览器入口、考试选项、学期开始日提示、本科课表、12节及考试列表。真实本科账号、验证码、学校在线回调与自动查询尚未用本人账号验证；模拟器仅核对入口、离线数据与界面，不代表认证成功。需学生在学校原网页完成这部分验证，不要求在聊天中提供密码。
+
+0.5.4登记冻结、V1.0材料、原签名以及反馈服务器部署文件均保持。反馈服务器仍由用户手动部署。
+
+## 实现决策
+
+保存接口增加可选页面有效性检查，并在串行保存队列内部执行；仅在界面检查会留下排队期间页面已变动的窗口。若误判会要求重新导入，原有调用保持兼容。最终独立审查结果记录于实现进度及后续交付记录。

-A new Flutter project.
+当前版本0.7.0+18，安卓包名 `com.tpschedule.app`。Dart包名保留 `hepan_everyday`，兼容既有代码引用。
 
-## Getting Started
+## 本科使用
 
-This project is a starting point for a Flutter application.
+在「我的 → 选择学校」选电子科技大学（本科生），通过学校原网页登录，打开课表并选学期，然后点击「导入当前课表」。导入新学校/学期后在课表页设置学期开始日。本科课表刷新和更新学期仍需在网页操作；本科考试页可选一个学期、多选期末/期中/补考缓考并自动读取。成功选项用于后续刷新，历史考试不改变课表。
 
-A few resources to get you started if this is your first Flutter project:
+本科显示12节，末节22:00–22:45；研究生和示例为11节。离线HTML/HTM及原JSON导入保持，教师/教室完整显示，课程名称详情可展开。

+## 开发与验证
 
-For help getting started with Flutter development, view the
-[online documentation](https://docs.flutter.dev/), which offers tutorials,
-samples, guidance on mobile development, and a full API reference.
+工具链、测试与构建入口见根目录README及 `scripts/android-env.ps1`、`scripts/build-android.ps1`。本目录运行 `flutter test --no-pub`、`flutter analyze --no-pub`；用Node运行 `test/school/*probe_js_test.cjs` 验证网页捕获。
+
+本科连接模块在 `lib/features/school/undergraduate/`，学校标识在 `lib/domain/school_identity.dart`。HTML解析不执行网页脚本，样例已脱敏；真实账号、验证码及在线SSO需本人在学校网页验证。
+
+不要删除、重建或分发根目录 `.tools/android-user/debug.keystore`；0.5.4登记冻结和V1.0材料不得用当前源码重生成。
